Towns and counties will have the power to impose fees on property owners to pay for upgrades to antiquated stormwater systems based on how much they contribute to runoff, under a bill signed into law Monday by Gov. Phil Murphy.

A decade-long battle to give local governments a tool to deal with storm runoff — the state’s biggest source of pollution for streams, rivers, and bays — ended yesterday with Gov. Phil Murphy signing a bill without fanfare that will do just that.

Gov. Phil Murphy pledged to end the practice of diverting funds from state affordable-housing and clean-energy programs, a budget tactic embraced by previous governors that he had continued, albeit not as aggressively as his predecessors.

"Governor Murphy and his administration have steadfastly stood by their commitment to 100 (percent) clean energy by 2050, and because of that, we are beginning to see the makings of a fossil-free New Jersey," said Ed Potosnak, executive director of New Jersey League of Conservation Voters, in a statement this morning.

This is how climate change will manifest in New Jersey, a reality that Gov. Phil Murphy, unlike his predecessor, acknowledges and has pledged to both resist and prepare for.

"Unless we do more (to counter climate change), the question isn’t whether we’ll see another superstorm like Sandy, but simply a question of when,” Murphy said during a speech in Highlands two weeks after his inauguration. “As the densest state in the nation, we can ill afford to keep our heads in the sand when it comes to climate change.“

“The governor’s first year has been a whirlwind of pro-environmental actions and commitments to conservation, including creating 100,000 jobs in energy efficiency, reversing rollbacks such as the Highlands Septic Density rule, standing up to polluters and developers, and making sweeping changes at the DEP that puts science-based decision making a top priority,” said Ed Potosnak, the fund’s executive director, who gave the Murphy administration a B+.

Two influential environmental groups gave Gov. Phil Murphy mixed reviews for his first year in Trenton, but both agreed the progress he initially made on key environmental issues has declined since his first 100 days in office.

The New Jersey Sierra Club issued a scathing scorecard on Monday, giving the Democratic governor a “D” for what it said was a “a lack of leadership on many key issues.” Murphy fared better last week with the New Jersey League of Conservation Voters, which gave him a “B+” for enacting “a whirlwind of pro-environmental actions and commitments to conservation.”
